| 2 | Preliminary focus on the mechanical and antibacterial activity of a PMMA-based bone cement loaded with gold nanoparticles显示文摘In total knee arthroplasty(TKA)and total hip replacement(THR)the restoration of the normal joint function represents a fundamental feature.A prosthetic joint must be able to provide motions and to transmit functional loads.As reported in the literature,the stress distribution may be altered in bones after the implantation of a total joint prosthesis.Some scientific works have also correlated uncemented TKA to a progressive decrease of bone density below the tibial component.Antibiotic-loaded bone cements are commonly employed in conjunction with systemic antibiotics to treat infections.Furthermore,nanoparticles with antimicrobial activity have been widely analysed.Accordingly,the current research was focused on a preliminary analysis of the mechanical and antibacterial activity of a PMMA-based bone cement loaded with gold nanoparticles.The obtained results demonstrated that nanocomposite cements with a specific concentration of gold nanoparticles improved the punching performance and antibacterial activity.However,critical aspects were found in the optimization of the nanocomposite bone cement. | T.Russo A.Gloria R.De Santis U.D'Amora G.Balato A.Vollaro O.Oliviero G.Improta M.Triassi L.Ambrosio | 2017 | Bioactive Materials2017,2,3: | 2 |

| 10 | Implications of crude oil pollution on natural regeneration of plant species in an oil-producing community in the Niger Delta Region of Nigeria显示文摘The study evaluated the impact of crude oil pollution on natural regeneration of plant species in a major oil-producing community in the Niger Delta region of Nigeria. Three sites—unpolluted site(US), polluted and untreated site(PUS), and polluted and treated site(PTS)—were purposively chosen for the study. The seedling emergence method was used to evaluate soil seed banks in the various sites at two depths, 0 to 10 cm and 10 to 20 cm. Woody-plant species richness, abundance, and diversity were higher in the US seed bank than in the PUS and PTS seed banks. The highest number of non-woody plants was observed in the US, followed by the PTS, and then the PUS. Both species richness and diversity of non-woody plants were highest at the US, followed by the PUS, and lowest in the PTS. Woody species in the US seed bank were 87.5% and 80% dissimilar with those of the PUS and PTS at 0–10 cm and 10–20 cm respectively. No variation was observed between woody species in the PUS and PTS seed banks. Non-woody species at 0-10 cm US seed bank were 73.08% dissimilar with those of PUS at the two soil depths and 81.48/88.46% dissimilar with those of the 0–10/10–20 cm of the PTS respectively. At 10–20 cm, non-woody species of the US were 69.66% dissimilar with those from each of the two soil depths in PUS; and 73.91/81.82% dissimilar with those of 0–10/10–20 cm of the PTS respectively. Non-woody species variation between the PUS and PTS was higher at 10–20 cm than 0–10 cm. The poor seed bank attributes at the polluted sites demonstrates that crude oil pollution negatively affected the natural regeneration potential of the native flora because soil seed banks serve as the building blocks for plant succession. Thorough remediation and enrichment planting are recommended to support the recovery process of vegetation in the polluted areas. | U.D Chima G.Vure | 2014 | Journal of Forestry Research2014,25,4: | 0 |
| 11 | In situ sol-gel synthesis of hyaluronan derivatives bio-nanocomposite hydrogels显示文摘The main driving idea of the present study was the comparison between two different chemical modifications of hyaluronic acid(HA)followed by the development of nanocomposite hydrogels directly in situ by biomineralization of photocrosslinkable HA polymers through sol-gel synthesis.In this way,it has been possible to overcome some limitations due to classical approaches based on the physical blending of inorganic fillers into polymer matrix.To this aim,methacrylated and maleated HA,synthesized with similar degree of substitution(DS)were compared in terms of mechanical and physico-chemical properties.The success of in situ biomineralization was highlighted by reflect Fourier transform infrared spectroscopy and thermogravimetric analysis.Furthermore,mechanical characterization demonstrated the reinforcing effect of inorganic fillers evidencing a strong correlation with DS.The swelling behavior resulted to be correlated with filler concentration.Finally,the cytotoxicity tests revealed the absence of toxic components and an increase of cell proliferation over culture time was observed,highlighting these bio-nanocomposite hyaluronan derivatives as biocompatible hydrogel with tunable properties. | U.D’Amora A.Ronca M.G.Raucci S.M.Dozio H.Lin Y.Fan X.Zhang L.Ambrosio | 2019 | Regenerative Biomaterials2019,6,5: | 0 |
